An RFID insert includes a housing of molded plastic construction and an
RFID tag captured within the housing. A portion of the housing is
permanently frangibly removable from the remainder of the housing to
remove the RFID tag from within the housing and thereby disable RFID
operation of the insert. The housing preferably includes a center portion
connected to a ring-shaped periphery by a plurality of angularly spaced
frangible bridges. The center portion of the housing may include a slot
or pocket for engagement by a tool to twist the center portion with
respect to the periphery and thereby facilitate rupture of the bridges,
and/or may include indicia to identify presence of the RFID tag in the
insert.
